I use the US2 transducer and get nothing but interference. So I spent the $60.00 and Iím waiting for my new external transducer to get here. Personally I think itís a load a [censored] you spend good money and then have to turn around and send Humminbird more money so it works like it should. Humminbird should have something set up with a transducer exchange for free. Last I checked Humminbird used to be about great service?

Have you checked the fuse in the head of the trolling motor? There is a 3amp fuse in there for the Us2 transducer. If its blown it will cause RFI

does the us2 cable on the Ultrex plug in to your sonar or do you need an adapter cable. I have a Terrova and had to buy a cable. I want to upgrade my sonar but I will need to add $30 to $40 buck to the price.

You'll need an adapter cable but if you had a US2 before the adapter should work. I came from a Fortrex to the Ultrex and used the same adapter. I can only speak to Lowrance graphs.

or you can sell your used adapter for $20 and be out about $10 switching graphs.
